    Deformities in Hatchling BP

    Hey I was just wonder how common it is to see deformities in hatchlings? Not in like morphs with known issues.

    I was just wondering because this year I hatched a Calico Spider OD and she was born with only one eye. Pairing was Calico Spider x Super OD Pinstripe.

    I dont think it was incubation related or genetic. The parents have had great babies with no problems before. The rest of that clutch was perfect. Incubator temps were spot on the entire incubation. I use a ve200 on a c serpents hot box Incubator. Temps are between 89/90 and never fluctuate more then half a degree.

    Anyway not really trying to figure out why just wondering how common deformities like that occur. Ive seen bps with no eyes before. This is my third season with and I've never personally experienced this and was just curious. Maybe someone with more experience can chime in.

    Also incase anyone is wondering she is doing great eating like a champ and is an absolute sweetheart. Gonna keep he as a pet and take her with to shows with me.

    Thanks,
    Sean

    Re: Deformities in Hatchling BP

    I find issues with about 1% of them...it sucks, but, it is part of nature...

    In the past I have seen random cases of spinal kinking.

    Not all deformities are visible though...last year (2021) I had two from the same clutch 2/9 that failed to thrive: I euthanized/necropsied one and used the info I gathered (deformed esophagus) to keep the other alive and comfortable as a 'special needs' pet.

    This year (2022) so far it looks like I may have one with a stub tail (on my GHI Line).

    Outside of expected deformities associated with specific morphs-I have been fortunate not to see eye-stuff yet (bad pun intended lol).

    Re: Deformities in Hatchling BP

    Sad to hear and sadder to see I’m sure. According to some of the literature temperature extremes and wide temperature fluctuations are the most common cause of eye issues barring the morph identifications that we know about. I think and am not absolutely sure but the genetic codes for normal structure and development not only in the egg, but prior to the shelling process can randomly become disrupted. So possibly it can be from a genetic foundation.

    Re: Deformities in Hatchling BP

    The reality is that in any organism, there are birth defects. We are very prone to thinking it is a morph issue or incubation issue, as there has been so much documented in both cases. Nevertheless, when everything is perfect and the morphs aren't known to be predisposed to complications, will still see defects and deformities. It's the nature of nature. There is the standard, and then there are the anomalies.

    This year I hatched 4 clutches that totaled 20 eggs and two of the twenty were boob eggs. I incubate at lower temps, about 87F. Everything came out beautiful, including the boob eggs, which were just very small because there wasn't as much mass to start with. One was 30 grams and one was 40 grams. However, I had one clown that came out looking fine other than it's head seemed a little small for the body. Not a pencil head, but just disproportionate by maybe 10% or 15%. It is having difficulties with locomotion. It can only move forward for the most part and cork screws badly. It does not withdraw from being touched on the nose, and it is almost never coiled but usually lies somewhat extended, if it isn't wedged with its head in the upper corner of the tub. I will be euthanizing it. There is no real reason for it. It just happened.

    Re: Deformities in Hatchling BP

    Hey rid, good to see you posting again! Welcome back! Yes, I touch and agree with you in that it happens in all life forms. However in the genetic codes there is a disruption in DNA and or RNA formulating correct cellular formation and structure in a normal fashion. Whether it’s the brain , the eyes, the spinal column, facial structures, cloacal formation. There just has to be a genetic/ physiologic explanation. In any case I always appreciate your expertise and this is purely my opinion. Welcome back again buddy.

    Re: Deformities in Hatchling BP

    Lee Russell McDowell (Vitamins in Animal Nutrition, on the web) has a summary of congenital defects caused by vitamin A deficiency in a variety of domestic animals. These are mostly mammals but also chicken and trout. In swine, congenital defects include both missing eyes and a large eye on one side and a small eye on the other side of the head.

    IMO, the above bears consideration as a possible cause of eye and other abnormalities in snakes, particularly the species that eat eggs in the wild.

    It is worth mentioning that snakes fed whole rodent prey are not at risk from hypovitaminosis A. Whole rodent prey is very, very high in Vit A.
